A Favicon is the little image displayed in your favorites and in the left corner of the Address Bar of Internet Explorer when you bookmark a page. The Favicon was first popularized by its appearance in the "Address Bar" and "Favorites Folder" using Internet Explorer. Currently, Internet Explorer 5.x (IE 5.x), Linux's Konqueror and Mozilla/Netscape 6.x (NS 6.x) Web browsers support the Favicon function.
